Provided are a method for measuring a state of a road surface, and a device therefor. According to one embodiment of the present invention, the method for measuring a state of a road surface comprises: a step of estimating an area of a target road surface included in a road area by using an image capturing the road area; a step of receiving an electromagnetic signal from and transmitting the electromagnetic signal to the target road surface by using a radar sensor; a step of receiving a reflected wave signal of the electromagnetic signal on the target road surface; and a step of estimating information on physical properties of the state of the road surface based on the reflected wave signal.
